corporatiql sof- Qliio Application December 5, 1947,.Sel1ia1 No. 789,896 3 Claims.z- (Gr-299 48) The present inventiorrrelatesto a dispensing hose and is concerned: primarily witha hose designed for use in conjunction with a gasolined-ispensing pump.

When an automobile drives up, to a gasoline pump, the range in which the automobile may p rk is. limi ed by t e, len t o e is sin hose. If this hose is long; the car'maybe parked in an accessible position over afairly wide rangea O h er ha d; if' he ho e s s o t is-r nge is materially limitedi lfn a ccordancewithwellac cepted' practice, one en'd' a gasoline hose isconnected to the pump adjacent to"thetop'there0f while the other end carries" a discharge'nozzle. This discharge: nozzle intended-f to-be'rec'ei'ved in a support. which is also" adjacent to the-top of he um hen the o zle n n; use r end of eliminating any snarling or entanglements in the hose, it has been thepracticeto limit; these hoses in length to a: degree corresponding'to-the height of the pumps, thatis', the bend-of the'hose between the fixed connection and thenozzle is located substantially"adjacent to-the ground.

Heretofore, the gasoline" pumps commonly m s al ed r und ser ice a io g r s n -t like have been'f'airlyj high with theresultthat a dispensing hose which is susceptibleof support thereby in the manner"above-indicated i'sreasonably long and aiiordsjthe required range-'in which the car maybeparked.

However; in accordance with certain recent trends in the gasoline pump industry, there-has developed the practice of; installingpumps that are materially shortenin-height; Following the old; known methods ofsupportirrg the-hose in po siti'on" when not inuse, this hasresultedin materially 1 reducing-' the range in which a 1 can may be parkedwith respect toanyparticular pump and stillbe in accessible positiom tohave its gasoline tank filled. With the foregoing conditions in": mind, this invention has in viewas its-foremostobjective the provision ofi'a gasoline pump including a hose that isextensible. Iiicarrying; out-thisvzidea; the invention proposestofollow the old practice of having that part of the hose which is locatedex-s teriorly of the --pump supported: in a; suspended position defined by a singlebight or bend:

Another important objectof theinventioni is the provision of a gasoline pumpi'togetherswith a dispensinghose withthe pump;:beinga;prov-ided with means for taking: up a portion or the extent of thehosethcrewithin'.

Still more in detail, the inventionx-haseas an object-the provision of a gasoline pump including asheave which is adapted to have taken upthere 2 on a portion of; a' gasoline dispensing hose. This sheave is mounted in the upper portion of the pump in a position in which it readily receives the hose and is provided with yieldable means normally retaining the hose in its wound-in or taken-up position.

In providing a pump and hose assembly in accordance with the above'noted thoughts, it becomes, important to provide for an effective conducting connection between the pumping mech anism proper and the end of the hose which is taken up on the sheave From the very nature of'its operation the sheave, is rotatable and this connection must a'c'commodate'this rotation. Accordingly; another highly important object of the invention is the provision of a gasoline pump including a rotatable sheave that is adapted to receive a hose together with conducting connections through the mounting of said sheave to the end of the hose which is, received thereon.

' In extending the hose into useful position and retracting it into its wound-up state, it is important that the hose be accurately guided so as to prevent snarling. With this thought in mind, a further object of the, invention is the provision of a gasoline pump which includes a dispensing hosev of the extensible type as above, indicated, together with means for guiding the hose as it is pulled'out or retracted. This means preferably takes the form of rollers that are suitably arranged" and which engage the hose with a guiding action.

Another highly important object of the. invention is the provision of suitable retaining means for assuring'that the hose remains in proper position on the sheave within the pump.

Various. other more detailed objects and advantages of the invention such as arise in connection with carrying out the above noted ideas in-a practical.embodiment will in part become apparentand in part be hereinafter statedas the description of the invention proceeds.

The invention therefore comprises a gasoline dispensing pump that is provided at the topportion with a sheave on which a portion of a dispensing hose is taken up. Mechanisrnis provided for guiding the hose and retaining it in position on the sheave together with means-for normally retaining the sheave in a wound-up or'hose-retracted position.

For a full or more complete understanding of the invention, reference may be had to the following description and accompanying drawings wherein:

Figure-1 isa perspective view of a, gasoline pumpwithacar positioned sufficiently; close 3 thereto to have a gasoline tank filled thereby. This view brings out the importance of having the hose extensible.

Figure 2 is a view in side elevation of the pump shown in Figure 1 on an enlarged scale.

Figure 3 is a view in end elevation of the pump shown in Figure 2 with a part of the bottom broken away.

Figure 4 is a top plan view with a portion of the pump casing at the top broken away. This view develops the take-up sheave and brings out the manner in which the hose is wound thereon.

Figure 5 is a view taken normal to the showing of Figure 4 of the upper portion of the pump with the casing broken away to bring out details of the take-up mechanism.

Figure 6 is an enlarged detailed view taken as a vertical section through the hub portion of the take-up sheave and associated mechanism.

Figure 7 is an enlarged detailed view bringing out the connection of the hose to the sheave hub. Referring now more particularly to Figure 1. a gasoline pump is illustrated therein and is identified in its entirety by the reference character P. This pump P is preferably of the new type in that it is not very high. Thus its top It is located fairly close to the base I I at the ground. An automobile is represented at A and is shown as including a gas inlet at l2. A dispensing hose H has a nozzle at l3 which must be fitted in the inlet l2 when the gasoline tank of the car A is to be filled. The other end of the hose I-I enters the pump at the point indicated at I4. It is evident outer peripheral portion 32 which is somewhat thinner. The inner thickened portion 3| carries a cylindrical wall 33 that is spaced from the tubular column 25. An oil seal designated 34, together with a, bearing assembly 35, is mounted in the recess defined by the base [9, column 25, thickened part 3|, and cylindrical wall 33. A packing ring 36 is interposed between the thickened portion 3i and the column 25. Immediately above the ring 36 there is a packing gland 31 which'carries a sealing ring 38 which is engaged by a spring 39. Another spring 40 is disposed outside of the'ring ,39 and engages the packing gland31.

' tom. This ring 29 includes a thickened part 4! that if the driver of the car A is to have fairly v wide latitude as to where he may park the car with respect to the pump P and still leave the inlet l2 in an accessible position, the hose I-I must be fairly long in extent. In fact, it must be longer than would be the case if its length were limited by the height of the pump P.

As shown clearly in Figure 3, the pump casing includes a recess at l5 that defines a notch or support for receiving the nozzle l3 when the latter is not in use. would be determined by the position of the points I4 and I5 and the height of the pump P.

The pump P includes a casing which is referred to generally by the reference character C. Enclosed within this casing C is a supporting structure that includes uprights l6 and horizontally disposed cross bars I! which support a table or cross plate l8.

Referring now more particularly to Figure 6, the table [8 is shown as carrying a base or pedes- Ordinarily, the length of the hose H carrying a cylindrical wall 42 which is spaced from the column 25 and which provides a, recess which receives a bearing assembly 43 and a sealing ring 44. A nut 45 carries a flange 46 which closes this recess and retains the ring 44 and bearing assembly 43 in assembled relation. This upper end plate 29 also carries a thinner peripheral portion 41 which is secured to the intermediate ring 30 by screw bolts shown at 15.

A packing gland48 is positioned about the column 25 at the top and is engaged by the outer spring 40. This gland carries another sealing ring 49 which is engaged by the spring 39, the sealing ring being a substantial duplicate of that at the lower end of the column.

A sheave is referred to in its entirety by the reference character S and includes an inner hub structure of sheet metal parts 50 and 5|. It will be noted that the sheave part 5i! is secured to the intermediate ring 30 by screw bolts shown at 52. The lower sheave part 51 is secured in a similar-manner to the ring 30 by headed screw bolts corresponding to screw bolts 52. The sheave S also includes a web structure at 53 which extends outwardly to the peripheral part formed with a groove 54 which actually receives the hose H.

It will be noted that the sheave S may be made of complemental halves which are substantial duplicates. Thus the upper half carries the part 55 and web 53 while the lower half carries the part 5| and the other web 53. These two halves tal. l9 which may be anchored thereto in any preferred manner such as by the headed bolts shown at 20. This pedestal I9 is formed with a central recess 2| with which communicates a passageway 22 that extends to one element of a coupling 23. A conduit 24 is also connected to this coupling and extends to the pump mechanism proper which supplies gasoline under pressure to the line 24. Extending upwardly from the pedestal I9 is a tubular column 25 that is closed at its upper end as indicated at 26. Intermediate its extremities the tubular column 25 is formed with a plurality of ports 21.

A hub assembly is mounted on the tubular column 25 for rotation thereabout. This hub is referred to generally by the reference character X and is intended to constitute the hub of a sheave as will be later described. This hub X comprises three main parts, a lower end plate 28, an upper end plate 25, and an intermediate ring 30. The lower end plate 28 comprises a, fiat ring-like portion having an inner thickened part 3i and an together define the. groove 54 at the outer pe-,

riphery. V

A spring housing is made up of two L-shaped members 55 and 56. The member 55 is anchored to the hub by one of the screw bolts 15, as shown in Figure 6, while the 'housing part 56 is anchored to the pedestal l9. A spiral spring '51 is received within the spring housing, one end of this spring being anchored to the housing part 55 and the other end to the housing part 56. The normal tendency of the spring 51 is to retain the hub X in the position shown in Figure 4 in which the-hose H is fully taken up on the sheave S to the maximum extent possible. When the hose is withdrawn into an extended position, the sheave S is rotated against the influence of the spring 51 so that when the extending tension is relieved the spring will return the hose to its normally wound position.

Referring now more particularly to Figure 7, it will be noted that one end of the hose H is anchored to the ring 36 as shown at 58. This connection may be achieved by having the end of the hose threaded and screwing it into a threaded socket. It is evident that gasoline under pressure may come through the conduit 24 through the coupling 23, passageway 22, through the recess 2|, and up through the column 25, whence it passes out the ports 21 into the space enclosed by the ring 30. The hose H is connected to this ring 30 at 58 and hence the communication to the hose is established. This communication remains in effect regardless how the hub X may be rotated or to what position it may assume.

,Carried by the uprights l6, cross bar IT, and table I8 at appropriate points are a plurality of guide rollers 59 which are disposed opposite to the peripheral groove 54 of the sheave S. These guide rollers serve to maintain the hose H in position in this groove. Each of the guide rollers 59 is mounted on a stud which may take the form of a headed bolt 60.

The casing C adjacent to the top is formed with a recess 6! around which is disposed a spout 62. This spout 62 carries a plurality of guide rollers 63 which may be arranged both horizontally and vertically as shown in Figures 4 and 5. The hose H passes between these guide rollers. The casing C inside the opening 6| may also carry a bracket 64- which in turn carries a plurality of guide rollers 65 which also aid in properly positioning the hose H.

Operation While the operation of the above mechanism is believed to be obvious, it may be briefly outlined by noting that the driver of the car A may park at any place within a fairly wide range from the pump P. With the car so stopped, the attendant grasps the nozzle 13 of the hose H and inserts it'into the inlet 12. In so positioning the nozzle, it may be necessary to extend the hose H. This may be done simply by applying sufficient tension on the hose to cause the sheave S to unwind against the influence of the spring 57. In so unwinding the hose pays out between the guide rollers 65 and '63. The pump mechanism proper is now started in operation to pump gasoline through the line 24, passageway 22, column 25, openings 21, to the connection at 58 where it passes through the hose H.

After the tank of the car A has been filled, the operator simply withdraws the discharge nozzle 13 and in straightening the hose substantially opposite to the spout 62, the tension is relieved so that the spring '51 is rendered efiective to rotate the sheave S in the opposite direction and wind a portion of the hose H thereon.

It will be noted that under ordinary conditions any sharp bend on the part of the hose H will be just adjacent to the spout 62 and will create sufiicient resistance to prevent the spring 51 from winding up the hose.

While a preferred specific embodiment of the invention is hereinbefore set forth, it is to be clearly understood that the invention is not to be limited to the exact mechanisms illustrated and described because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.
